Change in files ownership and flags after re-balancing

Description of problem:
after rebalancing on a extended volume(bricks added) the rights of the files in the volume changed to- ownership:root
-rw-r--r--. 1 root root 589824 Jul 17 18:00 368a8bf9-9990-43a1-8b1c-34d30c740628
and they were like this, before the rebalancing:
-rwxrwxrwx. 1 qemu qemu 589824 Jul 17 11:57 e168ec07-a1e2-485d-aa9d-a07d508e9f6c
Also every new file created in that volume is created with
-rw-r--r--. 1 root root, although the up directory is owned by qemu and before the rebalancing every new file was getting the proper flags and ownership.
Version-Release number of selected component (if applicable):
glusterfs-3.3.0-2.fc16- it is fedora package on Fedora 16
add bricks to stripe-replicated-distributed volume and rebalance it.
Steps to Reproduce:
1.Add bricks to striped-replicated-distributed volume
2. Make volume layer-fix
3. Make volume rebalance start
all the files in the volume and all the newly created change their owner to root and flags to "-rw-r--r--."- so 644.
to retain the behaviour before the rebalancing- every newly created file was owned by user:qemu, group:qemu. and flags 777.
all the time, i got:
[2012-07-17 13:08:38.671157] E [stripe-helpers.c:271:stripe_ctx_handle] 0-dis-magnetics-3-stripe-2: Failed to get stripe-size
[2012-07-17 13:08:38.671209] E [stripe.c:212:stripe_lookup_cbk] 0-dis-magnetics-3-stripe-2: Error getting fctx info from dict
but in the source rpm ChangeLog i saw that these two were already addressed in source commits. I'm not sure if these are related.
During the rebalancing there were some failures but i'm not sure if they're related to the root ownership thing- i'm sending the whole rebalancing log.
================All the failures on one host.

This seems to be a duplicate of bug 852361.
The issue was with rebalance creating destination files with root ownership. It would set the ownership to original after migration was complete.
But, since the user did not run with force option, the free space check (dst has less space than src) prevents migration, the link file would end up with wrong permissions.
